    help needed with RCD identification/wiring

    Hi I'd like to install an RCD in a shed, I have 2 good units that were removed from a working installation long ago that I'd like to use instead of buying a new one. The problem is that they don't have the 1-2-3-4 indicators on how to wire them and can't find their datasheet online/google Would...

    Two Lutron RA2 Switches - both switched on, and RCD trips, either on and no problems

    Only a DIY'er here, usually safe and competent enough to fix straight forward problems, but this one has me stumped. I have two outside lighting circuits running through Lutron RA2 dimmers. Both go back to a Hager MTN106 RCD. All been working fine for over a year, but now the breaker keeps...

    Replace rcd without replacing whole CU?

    Hi, could I ask for a second opinion please? My RCD failed routine 6 monthly testing using the test button. I'd like to get it replaced, and spoke to an electrician who said that he couldn't replace it without replacing the whole consumer unit because it didn't meet the the latest regs. It...

    RCD keeps tripping. Perhaps i've wired it incorrectly?

    Good afternoon! In my house, I have a three-phase power system and this RCD that's rated for 40 A max and 30 mA leakage current. It keeps constantly tripping on loads larger than a phone charger (ie an electric kettle or toaster). This house is to EU standards (I live in Latvia). I'm wondering...

    RCD tripping... What other problem determination can I do?

    Unfortunately my electrician is too busy installing EVs so I've kinda been left on my own for now! I have an issue where the RCD labelled #1 in the attached picture trips as soon as I attempt to turn the immersion heater on. I've had the immersion heater replaced (well, I couldn't get it out...

    Using armouring as earth and RCD protection

    Hi, If an SY cable is used to supply a consumer unit, and there isn't a guaranteed depth of 50mm for the wall it is in, would using the braiding as the earth negate the meed for RCD protection of that cable? Thanks

    Nuisance tripping - faulty RCD?

    Had a real headache of a fault finding job which has left me scratching my head - RCCB on a split load board, supplying 3 circuits (shower, immersion and downstairs lights) constantly tripping. The frustrating thing about this was while it would sometimes trip within seconds, mostly it would...

    Type AC RCD with solar inverter

    A friend of mine asked me to look at here PV system as she is not getting any power (and thus money) from it. First real issue is the Aurora inverter has a E031 fault which I suspect is burnt out relays, so I can probably fix that with a big iron and a couple of new relays (at last for another...

    Category for lack of RCD on sockets in 27 year old building

    There is a difference of opinion in that a testing company carrying out an EICR has classed lack of RCD protection as a C2 where I understand this type of fault to be a C3 according to Guidance Notes 3 Table 3.5. Their opinion has been formed in reference to a publication called EICR Code...

    Why would an RCD trip 3-4 minutes after a light has been turned off?
